When you have hard water, cloudy white stains build up on glass shower doors. This white film makes your shower doors look dirty even when they are otherwise clean. The buildup attracts soap scum and other dirt to create stains that require elbow grease to remove. While preventive measures are the best when it comes to hard-water stains, supplies found in the home help you successfully get rid of the film.
Hold a lemon half in your hand and sprinkle baking soda over the pulp side.
Scrub the surface of your glass shower doors using the baking soda-covered lemon half. Squeeze the lemon slightly as you scrub to release the juices. When there's no more juice in the lemon half, apply baking soda to another lemon half and continue scrubbing the glass shower doors until they're covered with the lemon and baking soda mixture.
Leave the lemon juice and baking soda mixture on the glass for 10 minutes. Dampen a sponge and scrub the shower doors to wash off the hard-water stains. Rinse your doors off to remove the cleaning mixture so you can see if any hard-water stains remain.
Combine equal parts lemon juice, white vinegar and water in a spray bottle. Spray the solution on any remaining hard-water stains on the glass shower doors. Allow the solution to remain on the stains for 10 minutes.
Dampen a clean cloth and wipe down your shower doors to remove the vinegar solution and the last hard-water stains. Dry the surface with another cloth.
